Homogeneous Diophantine approximation in S-integers

Edward Burger

Vol. 152 (1992), No. 2, 211–253
Abstract

In this paper we generalize classical results in Diophantine approximation to the setting of an arbitrary numher field in the context of the ring of S-integers. Specifically, we present theorems pertaining to simultaneous approximations of linear forms and develop the notion of badly approximable S-systems. In addition, we expand the subject of the geometry of numbers over the adèle ring of a number field by developing the concept of the adelic polar body. This theory is then used to produce transference theorems in this general situation.
